IV Series injection valves and IQ Series injection quills from Hayward Flow Control are designed to inject chemicals into a flowing pipeline away from the inner walls of the pipe or tank, ensuring rapid mixture and corrosion prevention.

The injection quills are available in PVC (Cell Class 12454 per ASTM D1784), CPVC (Cell Class 23447 per ASTM D1784) and PVDC to match a range of chemicals. The quills and injection valves have a built-in check valve with Hastelloy C spring to prevent the backflow of process liquid into the chemical feed line with the IV check being rebuildable.

“The injection valve has a seat that you can unscrew and repair or clean as needed,” says Patrick Heath, product manager for Hayward Flow Control. “That’s really the only difference between the two.”

Both the quills and injection valves have MNPT end connections and are pressure rated to 150 psi at 70 degrees F.

“There’s a double-threaded bushing at the dry end so you can thread the quill into the pipeline and connect your chemical pipe to the backside,” Heath says.

The injection quills are available in 1/2- and 3/4-inch sizes with 3-inch quills, and 1-inch diameter with a 4-inch quill. All sizes of the IV offer a 4-inch quill. Features include FPM O-ring seals and 45-degree bevel on the quill tip.

“We feel that the tapered end is the better choice as opposed to a flat end,” Heath says. “When it’s orientated correctly in the pipeline it helps to disperse the chemical more evenly.”

Options include flat bevel, BSPT or socket end connections and EPDM O-rings. 888/429-4635; www.haywardflowcontrol.com.
